Colin Ian King	745649c59a	spi: rockchip-sfc: Fix assigned but never used return error codes ... Currently there are two places where the error return variable ret is being assigned -ETIMEDOUT on timeout errors and this value is not being returned. Fix this by returning -ETIMEDOUT rather than redundantly assiging it to ret.
